What is the problem?
I have a CTC Bizer that connects to my RPi on /dev/ttyACM0. This printer was working fine with an older version of Octoprint (1.3.9). I was forced to upgrade when my old SD card with the image crashed and I rebuilt the OctoPi/Octoprint sw.
I have an Ender 3 Pro that connects on /dev/ttyUSB0 and that's working fine.
What did you already try to solve it?
The printer can be seen by the RPi.
